Two small games, built with the same rule as every tool on this site: everything runs on your device. No download, no install, no account, no "connecting to server…" screen, and no high-score table that phones home. Open a game, play it, close the tab — nothing is left behind except your own best score, stored in your browser.
The classic grid game. Eat, grow, don't bite yourself. Arrow keys or WASD, swipe on touch. Keeps your personal best.
Fresh 9×9 puzzles in three difficulties, every one with a single unique solution. Pencil marks, hints, conflict checking and a timer.
Why games on a privacy tools site? Because they are the clearest proof of the promise. A game that runs after you disconnect the network is not "mostly local" — it is entirely local. Everything you see on these pages is computed by your own device.
Most "free online games" are wrappers around a remote session: your keystrokes go to a server, ads reload every thirty seconds, and a script builds a profile of what you clicked. These two games do none of that. The page is a static HTML file with a few kilobytes of JavaScript; once it has loaded, your browser could be in aeroplane mode and the game would still be playable.
There is no account to create, so there is no email address to sell. There is no global leaderboard, so there is no server recording how long you played. Your best score and your puzzle progress live in your browser's local storage, on your own device, and clearing site data erases them permanently — there is no copy anywhere else to restore.
No. There is no endpoint to upload to. The games hold their state in JavaScript variables and, for your best score, in your browser's local storage. Advertising on this site is served by Google AdSense, which operates in its own ad frames and never sees what happens inside the game — and you can reject advertising cookies with the cookie notice without affecting either game.
Yes. No payment, no premium tier, no "watch an ad to continue". They are here because a site full of utilities is a nicer place with a break in it.
Once the page has loaded, yes — try it: load Snake, then switch your network off. The game keeps running because there is nothing left to fetch.
Only on your device, in local storage. If you clear browser data or use a private window, the record goes with it.
Possibly — the same rule applies to anything new: it has to run completely on your side. If you have a suggestion, the chat button on any page can turn it into an email.
